1. This leads to the development of a single sub-parallel joint set . 2. Continued deformation may lead to development of one or more additional joint sets . 3. Byrd and I insisted on one joint set of hearings. 4. In some cases, joint sets can be a tectonic-hydraulic hybrid. 5. As a result, they occur as families of joints that form recognizable joint sets . 6. Hydraulic joints occur as both nonsystematic and systematic joints, including orthogonal and conjugate joint sets . 7. Hold for several minutes while the icing joints set . 8. These layers appear rectangular, featuring orthogonal joint sets . 9. When the dihedral angles are nearly 90?within a joint system, the joint sets are known as " orthogonal joint sets ". 10. When the dihedral angles are nearly 90?within a joint system, the joint sets are known as " orthogonal joint sets ".
